So, I have a 2008 MacBook Pro loaded with Parallels 5 and Windows 7. The computer has recently seen an extreme slow down, probably because I have reached its limits. Now I just purchased a 2011 MacBook Pro 2.2Ghz 15" with the 750GB HD. I used Migration Assistant to transfer all my files over... Opening and closing windows has not improved. Loading iPhoto has not improved. Nothing seems to be running any faster on the new computer. Why? I'm running Mac OS 10.6.8 and iLife '11.
Could have a virus.
